Free, Downloadable, And Legal Horror Novel

An acquaintance emailed me about a horror novel that's free and legally downloadable off the web. His message:

"Hey, Kyu. I accidentally found this site, www.theinfected.co.uk. It's a horror novel, for free. It's going to be made into a movie, according to the link. I haven't read it yet, but since it's legal to get it I'm going to give it a try. Nothing to lose, right? Maybe PGS genre readers will be interested. You want to blog about it?"

My acquaintance is right: nothing to lose. The publishers have made the free download legal, so I guess that's okay. The book is Autumn, by David Moody. Its premise reminds me of "I Am Legend": virus kills many, and the dead become monsters. I don't think I can get to it right away anytime soon because of work and my own backlog of books, but those of you who can and do try it, comment away and let us know what you think of the story.
